Nobody wants to go to that Rhenna tour because the GP doesn't like when their pop stars go all artistic and ****. The GP doesn't want pop stars to grow and do anything other than be sexy and deliver Top 40 pop candy radio bops. Add that to the fact that the promo was a mess and it took her 4 years to come out with a new album.
She flopped. This is the first flop in her career. She'll recover. Next year, no sooner than that. Let the floppage of ANTi subside.
